Description

Technical Field

[0001] The utility model relates to the technical field of paper strength testing, in particular to a strength testing device for paper production. Background Technique

[0002] Paper is a thin and flat material used for writing, printing, painting, packaging, etc. It is usually made of cellulose materials such as wood pulp, waste paper or cotton fibers, and is formed through a series of processing and pressing. There are different types and uses of paper, including ordinary writing paper, packaging paper, art paper, cardboard, etc. It can also be processed according to different needs, such as coating, printing, etc., to meet specific usage requirements. Paper is a very common and important material, with wide applications in daily life and industrial production.

[0003] Paper production refers to the entire production process from raw materials to the final product. Usually, wood pulp, waste paper, bamboo, etc. are used as raw materials, and then the raw materials are processed through crushing, bleaching, etc. to form pulp, which is the basic raw material for making paper. Then the pulp is placed on a paper machine and formed into paper through processes such as forming, pressing, and drying. The entire paper production process requires strict control of the quality of raw materials, the stability of production processes, and the quality inspection of products to ensure the production of high-quality paper products. Therefore, it is necessary to test the strength of paper during the production process. Most of the current paper testing devices on the market can only be used to detect the compressive strength and surface roughness of paper, and cannot measure aspects such as the tensile strength and tear strength of paper. Moreover, most of the testing devices on the market are cumbersome to operate and cannot be simply operated to fix papers of different thicknesses. Content of the Utility Model

[0004] The purpose of the utility model is to provide a strength testing device for paper production to solve the problems raised in the above background technique.

[0005] To solve the above technical problems, the technical solution adopted by the utility model is:

[0006] A strength testing device for paper production includes two bottom plates. Both upper ends of the two bottom plates are fixedly connected with a first support plate. The upper ends of the two first support plates are jointly fixedly connected with an upper support plate. The lower end of the upper support plate is fixedly connected with a second propulsion structure. A clamping structure is arranged below the second propulsion structure. The clamping structure is used to fix the test paper. A first propulsion structure is arranged in the middle of the two clamping structures. The first propulsion structure is used to drive the clamping structure to lift and lower. Two guide rods are jointly fixedly connected to the opposite surfaces of the two first support plates.

[0007] A further improvement of the technical solution of the present utility model lies in that: the clamping structure includes a second support plate. On one side of the upper part of the second support plate close to the first support plate, there is a first rotation hole penetrating through the side of the second support plate close to the first support plate and extending to the side of the second support plate far from the first support plate.

[0010] With the above technical solution, in this solution, the worm makes a meshing movement with the support seat structure, thereby driving the bearing to rotate.

[0011] A further improvement of the technical solution of the present utility model lies in that: the support seat structure includes a worm gear. A first sliding groove is opened in the middle of the worm gear. A ring block is rotatably connected to the inner cavity of the first sliding groove. The side of the ring block close to the second support plate is fixedly connected to the side of the second support plate close to the support seat structure.

[0012] With the above technical solution, in this solution, the ring block provides support for the rotation of the worm gear, and then uses the cooperation of the first sliding groove and the ring block to limit the running track of the worm gear.

[0013] A further improvement of the technical solution of the present utility model lies in that: the protective cover structure includes a first housing. The side of the first housing close to the second support plate is fixedly connected to the side of the second support plate close to the protective cover structure.

[0016] The above technical solution is adopted, in which the rotation of the diaphragm drives the rotation of the rotating plate 1 and the rotating plate 2 respectively, and then drives the rotation of the connecting block 1 and the connecting block 2, thereby driving the two clamping structures to move.

[0017] A further improvement of the technical solution of the utility model is that a guide hole is symmetrically opened on one side of the guide plate close to the support plate one and extends through the side of the guide plate close to the support plate one and extends to the side of the guide plate away from the support plate one, and the inner cavities of the two guide holes are respectively slidably connected to the outer surface of the guide rod on the same side.

[0018] By adopting the above technical solution, the two guide holes and the two guide rods cooperate with each other, so as to prevent the clamping structure from being derailed during movement.
